這篇論文包含兩個雷射二極體驅動電路，其中之一可操作在1.25 Gbps，另外一個的位元傳輸速率則可達2.5 Gbps，此兩者都包含了驅動電路、自動功率控制電路和參考電壓產生電路; 另外，在2.5 Gbps的版本中，我們加上對偏壓電流和調變電流做數位控制的電路。這兩個雷射二極體驅動電路都是以TSMC 0.35 um 1P4M的數位製程來製作晶片，而1.25 Gbps版的晶片經過測試後證明其可操作在1.2 Gbps，並且自動功率控制電路與參考電壓產生電路也可正常運作。 Two laser diode drivers, of which one is operated at 1.25 Gbps while the other at 2.5 Gbps, are presented in this thesis. Both of them contain a driver, a reference voltage generator, and an automatic power control circuit. In addition, digital control blocks of bias current and modulation current are included in the 2.5 Gbps laser diode driver. TSMC 0.35um 1P4M digital process is used to fabricate these chips. The experimental results demonstrate that the 1.25 Gbps version can work at 1.2Gbps and APC works well, too.
